The only way to trigger the buzzer with bcs is to install another SSR. I came across this in my own build. I luckily had a small spare SSR I used to wire it in. Since the buzzer is 110v, the BCS won't be able to control it directly. In fact, BCS was designed to use an audible sound through the computer, not a physical buzzer.
Kosmo, if you need more visuals as to how your wiring up P-Js schematic with BCS, I may be able to help. When I built mine I had tried to go off my own schematic, but wound up with a hybrid of mine and P-Js after the way I had planned didn't perform as I would have liked it to.
